    Western blot analysis of extracts from Hela (lane 2(20μg)), HepG2 (lane 3(20μg)), a431 (lane 3(20μg)), 3T3 (lane 3(20μg)) and PC-12 (lane 5(20μg)) using Cyclophilin B Mouse mAb. Proteins were transferred to a PVDF membrane and blocked with 5% non-fat milk in TBST for 2 hour at room temperature. The primary antibody (1/1000) and Loading control antibody (beta Actin, HY-P83730, 1/5000) was used in 5% non-fat milk in TBST at 4°C overnight. Goat Anti-Rabbit/Mouse IgG-HRP Secondary Antibody (1/10000) was used for 1 hour at room temperature.

Background

  • Function

    Cyclophilin B (CyPB), encoded by PPIB, is an endoplasmic reticulum (ER) -resident peptidyl-prolyl cis-trans isomerase that catalyzes proline isomerization and supports protein folding within the secretory pathway[1][2]. Mechanistically, CyPB functions as a major folding catalyst for type I collagen by accelerating the rate-limiting cis-trans conversion of proline residues required for triple-helix formation[3][4][5]. CyPB also operates within the P3H1/CRTAP/PPIB complex, which is essential for procollagen folding and prolyl 3-hydroxylation in the ER, linking its enzymatic activity to collagen biosynthesis and extracellular matrix assembly[6][7]. In disease models, PPIB deficiency disrupts collagen post-translational modification, delays procollagen folding, alters collagen cross-linking, and causes recessive osteogenesis imperfecta with defective connective tissue formation[8][9][10][2]. Compared with other rough ER-resident peptidyl-prolyl isomerases, CyPB has a particularly prominent role in collagen maturation because collagen molecules contain abundant proline residues that require efficient isomerization during biosynthesis[5][11]. Structural and biochemical studies further demonstrate that CyPB interacts with calnexin-associated folding machinery and collagen-processing complexes, highlighting its specialized ER chaperone function rather than a generalized folding role[2][6]. For experimental applications, cyclosporin A binds the active site of CyPB and inhibits its isomerase activity, providing a widely used pharmacological tool for investigating collagen folding, ER protein maturation, and connective tissue biology[2][4].
